Chandrayaan II is slated for the second quarter of 2018, but before that comes a GSLV Mk-II mission carrying the GSAT 6-A satellite - in February - which will be followed by a flight of the GSLV Mk-III, India’s heftiest rocket to date fitted with a functional cryogenic engine.

Surrey Satellite Technology Ltd. (SSTL) has signed a £25M contract in Beijing with Twenty First Century Aerospace Technology Co., Ltd. (21AT) to provide data from a new Earth Observation (EO) satellite (SSTL-S1) that is due for launch via an ISRO PSLV launch vehicle mid-year.

As a part of the three-year short-term action plan, immediate missions that we plan to do this year are the GSLV-F08 that will launch the GSAT-6A communication satellite [around February]. Then we will have a PSLV mission with navigation satellite IRNSS-1I. Then comes the second developmental flight D2 of GSLV-MkIII. It will launch the high throughput satellite GSAT-29. Later, GSAT-11, which will be our heaviest satellite as of now, will be launched from Kourou. The Chandrayaan-2 mission will be launched this year on another GSLV.

Launch is set for 24th March. GS1 (1st stage) and GS2 (2nd stage) integration have been completed. Cryogenic upper stage has been shipped to launch site and GSAT-6A is fully assembled undergoing final stages of testing.

The 5,725-kg satellite, which will carry 40 transponders in the Ku-band and Kaband frequencies, is capable of “providing high bandwidth connectivity” with up to 14 gigabit per second (gbps) data transfer speed. “We will launch Gsat-11 from the European spaceport as it’s a fivetonne satellite. Around the same time in May, Isro will launch Gsat-29 through our GSLV Mk III rocket from Sriharikota. We also plan to launch Gsat-20 from India by next year,” the Isro chief said.

Are the other scheduled launches, of GSLV Mark 3 with GSAT-29, a second GSLV Mark 2 with GSAT 7, plus PSLV missions with Oceansat-3 and Risat-1A, all on course?

From what i know GSLV MK-3 with GSAT-29 is still on track for june-july launch. There will be a second GSLV MK-2 launch this year but it will carry Chandraayan-2 not GSAT-7A. GSAT-7A is set for launch sometime next year.

As for PSLV isro has been very quiet on missions beyond C41 so no clue.

Eagerly awaiting this launch, the largest Indian made satellite. 5 tonnes, almost as compelling as a PSLV or GSLV launch. May be historic in the sense that it is possibly the last Indian satellite to be sent up by Arianespace.
